Description

DC Isolator Switch – 4 Pole, 1500V, DIN Rail (YRO YRDS1 Series) | Lockable Solar Disconnect

Ensure safe and reliable isolation of your high-voltage DC solar circuits with the YRO YRDS1 Series 4-Pole DC Isolator Switch — a heavy-duty, lockable rotary disconnect switch engineered specifically for photovoltaic systems operating at up to 1500V DC. Designed for cutting off high-voltage DC current between solar panels and inverters, this isolator provides a safe physical firewall between your PV array and the rest of your electrical installation — protecting both personnel and equipment during maintenance, fault conditions, or emergency shutdowns.

The distinctive yellow body and red lockable rotary handle make the switch status unmistakable at a glance, with three clear positions: I (ON), O (OFF), and LOCK — where the handle can be padlocked in the OFF position to prevent accidental re-energisation during servicing, in full compliance with lockout/tagout (LOTO) safety procedures. The 4-pole configuration allows it to disconnect up to 2 MPPT string lines simultaneously, while the non-polar design means it can be installed in any orientation without affecting performance. Silver-plated contacts and a fast arc suppression time of ≤3ms ensure safe, reliable disconnection even under full DC load.
