Frequently Asked Questions

What cable sizes can be connected to the ESB16-11N-06 modular contactor?

The ESB16-11N-06 can accommodate flexible cables up to 6mm² maximum size. This capacity is suitable for most 16A circuit applications and provides adequate connection options for both power and control wiring in typical lighting and heating installations.

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

The ESB16-11N-06 modular contactor is designed for higher current switching (16A) compared to standard control relays, making it suitable for directly controlling lighting and heating loads. It features a hum-free AC/DC coil design and robust contacts specifically engineered for frequent switching of electrical loads, whereas standard relays are typically used for low-current control applications.

How do I mount the ESB16-11N-06 in my electrical panel?

This modular contactor mounts directly onto standard 35mm DIN rail and occupies just 17.8mm width (approximately 1 module space). The compact dimensions of 85mm height × 17.8mm width × 64.8mm depth ensure it fits in most standard distribution boards alongside other DIN rail mounted devices.

Can this contactor be used for both AC and DC control circuits?

Yes, the ESB16-11N-06 features an AC/DC coil design that operates with both AC and DC control voltages at 230V. This versatility makes it suitable for various control system configurations and eliminates the need for separate contactors for different voltage types.
