Eaton HLW3630V Series C Molded Case Circuit Breaker | 630A 3-Pole 690VAC

Eaton HLW3630V Series C Molded Case Circuit Breaker – 3-Pole, 630 Amps, 690VAC / 250VDC

The Eaton HLW3630V is an L-Frame Moulded Case Circuit Breaker (MCCB) for industrial use that provides heavy-duty branch circuit protection from high electrical loads. This full breaker assembly is part of Eaton’s proven Series C family, combining an adaptable thermal-magnetic trip unit with outstanding clearing capabilities. It is designed for high voltage distribution networks up to 690VAC and 250VDC, and is an essential asset for severe environmental installations, heavy industrial gear and maritime electrical switchboards.

The HLW3630V is equipped with a generous 630A continuous current rating and an impressive 70 kAIC interrupting capacity at 415VAC, which provides confidence in system stability and protects downstream equipment from catastrophic short-circuit and overcurrent conditions.

Technical Specifications

Features and Benefits

1. High Capacity Interrupting Rating: 70 kAIC breaking capacity at 415VAC, withstands severe thermal and mechanical strains during fault circumstances.
2. 50°C Ambient Temperature Calibration Factory calibrated for high temperature operating zones, identified by “V” suffix, to reduce nuisance tripping in restricted enclosures.
3. Thermal-Magnetic Trip (Interchangeable) Versatile T207 trip device with long-time thermal overload monitoring and instantaneous magnetic short-circuit clearance.
4. Heavy Duty Dual Voltage Capability – Safely accepts up to 690VAC alternating current distribution and up to 250VDC direct current loops.
5. True L-Frame Durability: Heavy duty, arc-resistant composite housing designed to withstand extreme vibration, mechanical shock and industrial abuse.

Our Engineer Expert’s Guide:

Electrical equipment in engine rooms or steering gear compartments is often subjected to temperatures in excess of 40°C. From the marine engineering point of view, Standard commercial breakers are normally rated at 40C, and will derate a lot, or nuisance trip, in these conditions.

The Eaton HLW3630V is calibrated at the factory specifically for 50°C. This makes it a suitable drop-in solution for vessel refits, main switchboards and high duty engine room ventilation busbars where thermal stability is of critical importance.
