Rich Solar RS-i4 DC Isolator Switch

The Rich Solar RS-i4 DC Isolator Switch provides a secure way to disconnect DC power between your solar array and downstream equipment. Built for outdoor use, it is designed for on-grid and off-grid solar applications where safe isolation, fast shutoff, and reliable installation matter.

DC power disconnect 4-pole / 2-string Outdoor rated On-grid & off-grid use
⚡

Fast DC Disconnection

Quickly disconnect DC power from the solar array to the charge controller, batteries, or inverter when maintenance, shutdown, or service access is needed.

🔒

SAFE-LOCK Operation

The isolated SAFE-LOCK handle uses three rotational positions to help reduce tampering and support more controlled solar system operation.

☔

Outdoor Solar Ready

Built for outdoor solar electrical installations and suitable for both off-grid and on-grid applications.

Product Overview

The Rich Solar RS-i4 DC Isolator Switch is designed to safely isolate DC power in solar energy systems. It helps create a more serviceable electrical layout by allowing the solar array to be disconnected from charge controllers, batteries, inverters, or other downstream components.

This model is built for 4-pole and 2-string applications, making it a practical choice for solar systems that require a larger DC isolation setup than a basic single-string disconnect. Its input and output connections are designed for easier installation, while the lockout option adds another layer of control during service or system shutdown.

Frequently Asked Questions

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

Why does the two-string RICH SOLAR disconnect use four poles instead of two? This model supports two PV strings and provides 4 poles in series for their disconnect arrangement. It differs from the one-string, 2-pole version, so choose from the actual number of circuits and the wiring diagram rather than enclosure size. Can I combine two PV strings inside the 4-pole quick-disconnect enclosure? The page identifies support for two strings but does not describe the unit as a fused combiner. String combining, reverse-current protection, conductor sizing, and parallel-source rules require separate confirmation from the system design and applicable electrical standard. What must be calculated before applying the 1,500V 40A ratings to both strings? Check each string's cold-weather open-circuit voltage, operating and short-circuit current, parallel-current effects, conductor ratings, derating, and the connected equipment's input limits. The published 40A thermal rating is not a substitute for those calculations. How is the dual-string PV switch protected for an exposed installation? The enclosure is listed IP66NW and uses flame-retardant UL94 V-0 polycarbonate, with operation from -40°F to 158°F. Maintain the rating with appropriate cable entries, mounting orientation, supports, sealing, and service clearances. Can the 4-pole disconnect be locked off while servicing downstream solar equipment? Yes. Its isolated SAFE-LOCK provides three rotational positions and a lockout option. Locking the switch protects against casual operation, but the array remains live on the line side and all sources must be identified and verified under the service procedure. Does the dual-string switch interrupt a DC arc as quickly as the one-string model? RICH SOLAR publishes an arc-suppression time under 3ms for this 4-pole model. If a switch shows heat, damage, water intrusion, or difficult operation, de-energize it safely and inspect the installation rather than relying on the stated opening speed.
