Eaton hmcp circuit breaker


G-Frame circuit breakers are factory sealed. With less than pickup voltage applied to the undervoltage release mechanism, the circuit breaker contacts will not touch when a closing operation is attempted. An inch Accessory installation should be done before the circuit breaker is mounted and connected. The undervoltage release mechanism monitors a voltage typically a line voltage and trips the circuit breaker when the voltage falls to between 70 and 35 percent of the solenoid coil rating. Leads are orange and brown. Suitable for mounting in right pole only of two- or three-pole breaker.

    Motor Circuit Protectors (HMCP)

    Eaton's Motor Circuit Protectors are UL Recognized instantaneous-only breakers for motor short-circuit protection. When used in tested motor starter.
    Select shunt trip catalog number for the voltage within the indicated voltage range. A maximum of one point terminal block can be installed on the right side of the circuit breaker for the internal accessories.

    The undervoltage release mechanism consists of a continuous rated solenoid with a plunger and tripping lever mounted in a plug-in module. With less than pickup voltage applied to the undervoltage release mechanism, the circuit breaker contacts will not touch when a closing operation is attempted. Cutoff provisions required in control circuit. Accessory installation should be done before the circuit breaker is mounted and connected. F-Frame circuit breakers are factory sealed.

    Auxiliary Switch The auxiliary switch provides circuit breaker contact status information by monitoring the position of the molded cross bar that contains the moving contact arms.

    The shunt trip consists of an intermittent rated solenoid with a tripping plunger and a cutoff switch assembled to a plug-in module.

    Flux paths surrounding permanent magnets used in the shunt trip assembly hold a charged spring poised in readiness to operate the circuit breaker trip mechanism. Where specified, fixed-mounted accessory terminal blocks are available. The undervoltage release mechanism monitors a voltage typically a line voltage and trips the circuit breaker when the voltage falls to between 70 and 35 percent of the solenoid coil rating.

    The plug-in module is mounted in retaining slots in the top of the trip unit. Marking label included with accessory kits. Undervoltage release mechanism coils are designed to be applied at specific AC or DC voltages within the voltage range shown on applicable circuit breaker accessory nameplates. However, with a proper control voltage source, they may be applied in place of conventional trip devices for special applications.

    When a microfarad capacitor charged to 28 Vdc is discharged through the shunt trip coil, the resultant flux opposes the permanent magnet flux field, which releases the stored energy in the spring to trip the circuit breaker.

    Shunt Trip. Accessory installation should be done before the circuit breaker is mounted and connected. Accessory Terminal Block R-Frame.

    Undervoltage Release Mechanism The undervoltage release mechanism monitors a voltage typically a line voltage and trips the circuit breaker when the voltage falls to between 70 and 35 percent of the solenoid coil rating.

    As the circuit breaker resets, the shunt trip reset arm is actuated by the circuit breaker handle, resetting the shunt trip.

    Comments

    1. With less than pickup voltage applied to the undervoltage release mechanism, the circuit breaker contacts will not touch when a closing operation is attempted. Terminal Block Same Side.

    2. Leads exit load end of circuit breaker. Electrical ratings are also shown on applicable circuit breaker accessory nameplates.

    3. Does not function with manual switching; however, it will operate when either a shunt trip or undervoltage release is operated. A maximum of one point terminal block can be installed on the right side of the circuit breaker for the internal accessories.

    4. As the circuit breaker resets, the shunt trip reset arm is actuated by the circuit breaker handle, resetting the shunt trip. Undervoltage Release Mechanism.

    5. Select handle reset undervoltage release mechanism catalog number for the voltage within the indicated voltage range.
