Himel HDP6 Motor Protection Circuit Breaker (MPCB) — 3-Pole, 0.1A to 80A, 100kA

The Himel HDP6 Motor Protection Circuit Breaker (MPCB) is a 3-pole thermal-magnetic motor protector that combines short-circuit, overload, and phase-loss protection in one compact device. With an outstanding 100 kA breaking capacity (Icu) and adjustable thermal trip settings, the HDP6 series protects three-phase motors from 0.06 kW up to 25 kW across a full current range of 0.1 A to 80 A.

Key Features

• Breaking Capacity (Icu): 100 kA — best-in-class short-circuit protection
• Adjustable thermal overload protection with rotary setting dial
• Fixed magnetic short-circuit trip for instant fault clearing
• Phase-loss / single-phasing sensitivity protects motor windings
• 3-pole, IP20, DIN-rail or screw mount
• Standard: IEC/EN 60947-4-1
• Rated insulation voltage Ui: 690V · Frequency: 50/60Hz

Applications

Direct-on-line (DOL) motor starters, pumps, fans, compressors, HVAC units, conveyors, and small genset protection. Combine with a Himel HDC3 contactor to build a complete motor starter. The HAE11 (1NO+1NC) auxiliary contact mounts on the side for remote status indication.

How to Select

Choose the variant whose setting range brackets your motor's full-load current (FLC). Set the dial to the motor nameplate current for correct overload protection.
