Phoenix Contact introduces the HMC series, their first 120 V_AC hydraulic-magnetic circuit breakers for use in Class I, Division 2 applications.

The UL-approved products utilize a fully sealed hydraulic-magnetic design that allows for accurate power switching and reliable overcurrent protection. Each breaker is rated for 50 V_DC and breakers up to 15 A are also dual-rated at 120 V_AC. They have a short-circuit current rating (SCCR) of 1 kA and a temperature operating range of -40°C to 65°C.

The HMC series offer pluggable line and load terminations along with the unique T-bus option that allows breakers to snap into a common power bus. These features ease installation and reduce wiring. The product housing utilizes a unique plastic material that allows for large temperature swings and stays flexible without cracking.
