Eaton HMCP100R3C Molded Case Circuit Breaker 100A 3 Pole 600V

SKU CH-KQ7D-6J2AM

A 100 A, three-pole molded case circuit breaker rated for 600 V AC and 250 V DC with a 65 kA interrupting capacity at 600 V AC, thermal-magnetic trip adjustable from 23 A to 84.5 A.

  • 100 A rated current handles heavy motor loads
  • 65 kA interrupting rating at 600 V AC clears severe faults
  • Thermal-magnetic trip protects against overload and short circuits
  • Adjustable trip range from 23 A to 84.5 A matches motor curves
  • Three-pole 600 V AC / 250 V DC design suits industrial power systems

Three-pole 600 V motor protection

The Eaton HMCP100R3C is a moulded-case circuit breaker rated for 100 A continuous current at 600 V AC and 250 V DC. It uses a thermal-magnetic trip unit with fixed instantaneous settings to protect three-phase motor circuits in industrial control panels. The frame size is 250 A and the interrupting rating reaches 65 kA at 600 V AC.

Adjustable trip range for starter coordination

The breaker provides a low amp trip setting of 23 A and a high amp trip setting of 84.5 A, allowing the installer to match the instantaneous pickup to Eaton or Rockwell motor starters without additional accessories. This range simplifies selective coordination in multi-starter installations and reduces nuisance tripping during motor inrush.

100 A continuous duty with 65 kA withstand

The device handles full-load motor currents up to 100 A in free-standing mounting configurations. Its 65 kA interrupting capacity covers most 600 V distribution systems, while the 250 A frame provides mechanical headroom for future uprating within the same enclosure footprint. Applications requiring higher continuous current or adjustable instantaneous settings will need a different frame or trip unit.

Questions about this item

What is the fixed instantaneous trip threshold on the 100 A HMCP breaker?

The instantaneous trip is fixed at 84.5 A high setting and 23 A low setting, so the breaker will open at those currents without adjustment.

What is the maximum short-circuit current the 600 V breaker can safely interrupt?

The breaker carries a 65 kA AIR rating at 600 V AC, meaning it can clear faults up to that level without damage.

How much heat does the 250 A frame breaker dissipate when carrying 100 A continuously?

The thermal-magnetic trip unit is calibrated for 100 A continuous current in a 250 A frame, so heat rise stays within the frame's design limits during all-day operation.
