HQP3040H - 40Amp Circuit Breaker

HQP3040H - 40Amp Circuit Breaker

Matching a replacement circuit breaker means looking beyond the amp rating. The Eaton HQP3040H is a 40-amp, three-pole Quicklag thermal-magnetic circuit breaker with a 240V rating and a 10 kAIC interrupting rating. It uses plug-on mounting and has a non-interchangeable trip, two details that are especially important when checking compatibility with existing or legacy electrical equipment. Those measurements give you concrete numbers to compare with the breaker being replaced and the available equipment space.

Key Features and Benefits

• 40-amp rating — Provides a clearly defined current rating for comparison with the equipment requirements.
• Three-pole configuration — Matches equipment requiring the specified three-pole breaker arrangement.
• 240V rating — Gives you an exact voltage specification to verify during replacement selection.
• Quicklag thermal magnetic design — Identifies the manufacturer's specified breaker design and operating mechanism.
• HQP breaker type — An important compatibility detail when matching a breaker to existing equipment.
• Plug-on mounting — Defines the mounting method that should be checked against the equipment configuration.
• Non-interchangeable trip — Identifies the supplied trip configuration without implying field interchangeability.

Where It Works Best

The Eaton HQP3040H 40A 3-pole circuit breaker is appropriate for compatible existing and legacy electrical equipment that calls for this particular combination of specifications: 40 amps, three poles, 240V, 10 kAIC, HQP Quicklag type, plug-on mounting, and a non-interchangeable trip. Its physical dimensions—3.2 "W x 4.7 "H x 3.9 "L/D—should also be compared with the existing breaker and available equipment space.
