Product Description
Protect your high-voltage solar panel strings and lithium/lead-acid battery banks with the Ulterior 125A 2 Pole 1000V DC MCCB (Model: ULM3-125H). Standard miniature AC breakers fail to safely isolate high-potential DC arcs; this industrial-grade Molded Case Circuit Breaker is specifically designed to safely interrupt direct current loads up to 1000V DC at 125 Amperes.
Ideal for residential, commercial, and industrial solar installations, the ULM3-125H provides reliable dual protection against severe overloads and catastrophic short-circuit faults. It features a rugged flame-retardant molded casing, heavy-duty terminal connection bolts, phase partition barriers to prevent flashover, and an ergonomic toggle switch for clear manual operation. Fully CE certified and tested to international electrical standards, the Ulterior DC MCCB is the essential safety disconnect switch for modern solar PV arrays, energy storage setups, and high-voltage DC distribution systems.
