Rich Solar RS-BS275 275A On/Off Battery Switch

The Rich Solar RS-BS275 275A On/Off Battery Switch is built for safe battery isolation in RVs, vans, boats, trailers, solar battery systems, inverter setups, and other DC power applications. With a removable ergonomic knob, glass-fiber reinforced nylon enclosure, flexible surface or panel mounting, removable wiring windows, and a 275A continuous DC rating, this switch gives customers a clean way to disconnect battery power when servicing, storing, or protecting a DC electrical system.

275A Continuous DC rating for compatible battery, inverter, RV, marine, and solar power systems.
455A Intermittent DC rating for short-duration higher current demands up to 5 minutes.
1250A Cranking rating listed for 10 seconds in compatible DC system applications.
48V DC Designed for DC electrical systems up to the listed 48V DC voltage rating.

Product Overview

The RS-BS275 is designed to help customers safely shut off battery power when a DC system is not in use, during maintenance, or when equipment needs to be isolated. It is a practical add-on for battery banks, inverter systems, RV power builds, marine wiring, off-grid solar systems, and backup power setups.

The red on/off knob gives users a clear physical disconnect point, while the removable knob design can help prevent unauthorized or accidental use when isolation is needed.

Built for Safer Battery Isolation

A battery switch gives customers a simple manual disconnect point between the battery bank and connected DC equipment. That matters for servicing, storage, troubleshooting, transport, emergency shutoff planning, and preventing unnecessary parasitic draw when the system is not being used.

RV & Camper Systems Useful for isolating house batteries, inverter wiring, and DC loads during storage, maintenance, or travel.
Marine & Engine Room Use Meets ISO 8846 ignition protection, making it suitable for engine room installation when installed correctly.
Solar Battery Banks A practical disconnect option for battery-based solar systems, cabin power, off-grid setups, and backup banks.
Inverter Power Systems Helps create a clear manual isolation point between battery banks and supported inverter equipment.

Key Features That Matter

This description keeps the focus on the real buying decision: current rating, removable isolation knob, mounting flexibility, wiring access, enclosure durability, ignition protection, and terminal compatibility.

Removable Knob for Isolation

The ergonomic red knob is designed for easy on/off control and can be removed for isolation and safety. That helps prevent accidental switching or use when the battery system should remain disconnected.

Glass-Fiber Reinforced Nylon Enclosure

The robust glass-fiber reinforced nylon enclosure is built for demanding DC electrical environments where the switch may be mounted near batteries, inverters, solar equipment, or vehicle power systems.

Removable Wiring Windows

Removable windows help provide unobstructed wiring access, making it easier to route battery and inverter cables into the switch enclosure during installation.

M10 / 3/8" Terminal Studs

The switch uses M10 / 3/8" terminal studs, giving customers a clear connection point for properly sized battery cables, lugs, and DC wiring hardware.

Surface or Panel Mount Flexibility

The RS-BS275 can be installed using surface or panel mount options, giving customers more flexibility when planning battery compartments, inverter bays, marine electrical panels, RV storage areas, and off-grid power rooms.

That mounting flexibility makes it easier to place the switch where it can be reached quickly while still keeping cable routing clean and protected.

Frequently Asked Questions

Clear answers to common questions about this product, setup, compatibility, and use.

How do the continuous, intermittent, and cranking ratings differ on the RS-BS275 switch? RICH SOLAR publishes 275A continuous, 455A for 5 minutes, and 1,250A for 10 seconds. Size against the real duty cycle and equipment surge; a short cranking rating does not authorize a sustained load above the continuous rating. Can the 275A battery switch be installed in a 48V DC system? The switch is rated to 48V DC. The actual bank voltage, maximum charging voltage, fault current, load current, and switching arrangement must all stay within the manufacturer's requirements; never apply an AC rating or higher DC voltage by assumption. What cable lugs fit the terminal studs on the RICH SOLAR battery isolator? The RS-BS275 uses M10, or 3/8-inch, terminal studs. Match ring size and cable ampacity, observe the maximum hardware torque, prevent the lugs from rotating, and cover the terminals against accidental contact. Can the removable knob serve as the only safety protection in a battery circuit? The removable knob supports isolation and reduces unauthorized operation, but the switch is not a fuse. The circuit still needs correctly placed overcurrent protection, suitable conductors, secure mounting, and a procedure that confirms power is actually absent before service. Is the RS-BS275 suitable for an engine-room installation? RICH SOLAR states that it meets an ignition-protection standard and is suitable for an engine room. Its glass-fiber-reinforced nylon enclosure can be surface or panel mounted, but cable support, terminal covers, ventilation, and local marine or vehicle requirements still apply.
