HDM3 / HDM3E · Moulded Case Circuit Breaker
The Himel HDM3 (and electronic-trip HDM3E) moulded case circuit breakers are the workhorse protection at the heart of a switchboard. They provide overload and short-circuit protection for main incomers and sub-distribution feeders across a broad frame and current range.
For panel builders, the value is completeness: the HDM3 family covers common frame sizes, 3-pole and 4-pole options, and the accessories — shunt trips, auxiliary and alarm contacts, motor operators — that a compliant board needs. The HDM3E adds adjustable electronic trip for tighter discrimination.
Sourcing the MCCB alongside your Himel drives and contactors means one authorised supplier, one delivery and matched, genuine components.
