Frequently Asked Questions

What cable sizes can the ESB25-22N-06 modular contactor accommodate?

The ESB25-22N-06 can accommodate flexible cables up to 10mm² maximum size, providing sufficient capacity for most 25A applications while maintaining secure terminations in the compact terminal design.

What is the difference between this modular contactor and a standard contactor?

Modular contactors like the ESB25-22N-06 are specifically designed for DIN rail mounting in distribution boards and feature compact dimensions (36mm width). Unlike larger industrial contactors, they're optimised for building services applications with hum-free operation and typically handle lighting, heating, and small motor loads.

What are the mounting dimensions for the ESB25-22N-06?

The ESB25-22N-06 measures 36mm wide, 85mm high, and 64.8mm deep, weighing just 0.25kg. It mounts directly onto standard 35mm DIN rail and requires minimal panel space, making it ideal for crowded distribution boards.

Can the ESB25-22N-06 be used for both AC and DC control circuits?

Yes, the ESB25-22N-06 features a universal 230V AC/DC coil that operates with both alternating and direct current control systems. This versatility eliminates the need for separate AC and DC variants and simplifies inventory management.
