Why it Matters

The high-capacity four-pole switch.
The ESC463 sits at the top of Hager's four-pole normally open range, with a 63A AC1 rating for the heaviest multi-circuit and three-phase loads the modular series covers. All four normally open poles stay isolated at rest and close together when 230V AC is applied to the coil, so a single remote command – from a timer, control switch or building management system – switches a large three-phase-plus-neutral load or four separate circuits at once.

Rated for demanding feeds.
Hager rates the ESC463 at 63A for AC1 loads and 32A for AC3 motor duty, under the AC-7a/AC-7b utilisation categories for slightly inductive and household-motor loads. Terminals accept rigid conductors from 1.5 up to 25mm² (flexible to 16mm²) at a 1.2Nm tightening torque, matching the larger cabling a 63A four-pole feed runs, and endurance is rated at 100,000 mechanical operations with 30,000 electrical cycles for long life in continuously cycled circuits.

Plan space and cooling in the board.
The ESC463 occupies three DIN modules (54mm wide, 85mm high, 60mm deep) on standard 35mm rail, so budget the space beside your circuit protection. It operates from -10°C to 50°C to suit meter boxes, plant rooms and commercial distribution boards in Australian conditions, and with 21.5W dissipation at full load an LZ060 heat dissipation insert from Hager is strongly recommended where contactors sit side by side. An ESC080 auxiliary contact is also available.

Q: How much load can the Hager ESC463 switch?
63A for AC1 resistive-type loads and 32A for AC3 motor loads, across four normally open poles on a 230V AC coil.

Q: What cable sizes fit the ESC463 terminals?
Rigid conductors from 1.5 to 25mm² and flexible conductors from 1.5 to 16mm², at a 1.2Nm tightening torque.

Q: Does the Hager ESC463 need extra cooling?
At 21.5W dissipation under full load, an LZ060 heat dissipation insert is recommended where contactors are mounted side by side; it otherwise mounts on standard 35mm DIN rail.
