• 16A Current Rating with 2-Pole Configuration: Provides robust switching capacity for medium-load applications whilst maintaining compact dimensions for space-constrained installations.
• Normally Closed (NC) Configuration: Ensures circuits remain energised during normal operation, making it ideal for safety-critical applications and fail-safe systems.
• Universal 24V AC/DC Coil: Offers installation flexibility by accepting both AC and DC control voltages, simplifying system design and reducing inventory requirements.
• Compact DIN Rail Mounting: At just 17.8mm width, maximises panel space utilisation whilst ensuring secure, professional installation standards.
• 6mm² Cable Capacity: Accommodates substantial cable sizes for high-current applications without requiring oversized terminals or connections.
• IP20 Protection Rating: Provides appropriate protection for standard panel installations whilst maintaining accessibility for maintenance.

Applications

The ESB16-02N-01 modular contactor is widely used in commercial and industrial installations for switching and controlling lighting circuits, HVAC systems, heating elements, ventilation fans, electric vehicle charging stations, small motors and circulation pumps. Its normally closed configuration makes it particularly suitable for emergency lighting systems, security applications, and installations where loads must remain energised during normal operation. The compact design suits modern control panels, building automation systems, and retrofit applications where space is limited.

Standards and Sustainability

This ABB modular contactor carries UKCA, CE and UL certifications, ensuring compliance with British, European and North American electrical standards. The IP20 protection rating provides appropriate safety levels for standard panel installations, whilst the wide operating temperature range of -25°C to +55°C ensures reliable performance across diverse environmental conditions.

Frequently Asked Questions

What cable sizes can be connected to the ESB16-02N-01 modular contactor?

The ESB16-02N-01 accepts flexible cables up to 6mm², providing ample capacity for most 16A applications. This generous cable capacity ensures secure connections and reduces voltage drop in longer cable runs, making it suitable for both local and remote switching applications.

What's the difference between normally closed (NC) and normally open (NO) contactors?

The ESB16-02N-01 is normally closed (NC), meaning the contacts are closed when the coil is not energised, allowing current to flow through the circuit. When 24V is applied to the coil, the contacts open and interrupt the circuit. This configuration is ideal for fail-safe applications where loads should remain energised during normal operation.

How does the hum-free coil design benefit installations?

The AC/DC coil design eliminates the characteristic humming noise produced by traditional AC-only contactors. This makes the ESB16-02N-01 particularly suitable for installations in offices, schools, hospitals, and residential buildings where quiet operation is essential for occupant comfort.

What are the mounting dimensions and panel requirements?

The ESB16-02N-01 measures 85mm high × 17.8mm wide × 64.8mm deep and weighs just 0.14kg. It mounts on standard 35mm DIN rail, requiring minimal panel space whilst providing full 16A switching capacity. The compact width of 17.8mm allows multiple units to be installed in tight control panels.
