Why it Matters

The high-capacity switching option.
The ESC263 sits at the top of Hager's 2-pole modular contactor range, with a 63A AC1 rating for heavier single-phase and two-pole loads that the 25A and 40A models cannot cover. It keeps the same normally open logic – both poles open at rest, closing when 230V AC energises the coil – so it drops straight into remote switching schemes for large lighting installations, electric heating banks and pumping or ventilation circuits controlled from a timer or building management system.

Rated for demanding circuits.
Hager rates the ESC263 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 take rigid conductors from 1.5 up to 25mm² (flexible to 16mm²) to suit the larger cabling a 63A feed runs, and endurance is rated at 100,000 mechanical operations with 30,000 electrical cycles for a long service life in continuously cycled circuits.

Planning it into the board.
The ESC263 occupies three DIN modules (54mm wide, 85mm high, 60mm deep) on standard 35mm rail, so budget the space alongside your circuit protection in the switchboard. It operates from -10°C to 50°C, covering meter boxes, plant rooms and commercial distribution boards under Australian conditions, and with 11.5W dissipation at full load an LZ060 heat dissipation insert from Hager is worth considering where devices are packed tightly. An ESC080 auxiliary contact is also available.

Q: How much load can the Hager ESC263 switch?
63A for AC1 resistive-type loads and 32A for AC3 motor loads, on two normally open poles with a 230V AC coil.

Q: What cable sizes fit the ESC263 terminals?
Rigid conductors from 1.5 to 25mm² and flexible conductors from 1.5 to 16mm².

Q: Does the Hager ESC263 need extra cooling in the board?
It dissipates 11.5W at full load, so where contactors are mounted side by side an LZ060 heat dissipation insert helps manage heat; otherwise it mounts on standard 35mm DIN rail.
