HB-Series Miniature Circuit Breakers

Increase performance and save space with our Hydraulic Magnetic miniature circuit breakers.

The new universal-voltage HB-SERIES Circuit Breaker from Weidmuller is the latest addition to our Hydraulic Magnetic Circuit Breakers lineup. It features modularity, ease of use, and space-saving well beyond that of conventional circuit breakers.

The operational universal-voltage ranges from 240VAC/80VDC for 1 and 3 Poles, and 120/240VAC/80VDC for 2-Pole variants, which are available in 0.5-32 Amps in instantaneous, short, medium and long delay curves.

Features & Benefits

Visual Operational Indicator

Green/Off – indicates physical contacts are open allowing work on downstream circuit to be carried out safely.
Red/ON – “Circuit is Live” Conforms to IEC/EN 60947-2 for industrial isolation

Finger Safe Terminals

Touch safe with captive screws

Rising Conductor Cage Clamp

Excellent retention of ferruled, solid, or stranded wire.

Multi-stage Arc Extinguishing Chamber

Compact and well-proportioned blowout arc grid plates work to draw out, split, reduce, and extinguish arcs caused when opening a circuit.

Additional Features & Benefits

Advance Hydraulic Electromagnetic Tripping Mechanism

Hydraulic oil viscosity creates time lags longer or shorter at cold or hot temperatures
No thermal element, therefore resettable immediately after close
No derating necessary, 100% rated breaker
High Shock and Vibration endurance, 10G and 5G respectively.
