ABB WRB-600 Series Contactor Mechanical Latching Block, For Use With AF and NF Series Contactors - 1SBN040100R1011

This contactor mechanical latching Block is an add‑on device that provides mechanical retention for AF and NF series contactors, enabling the contactor to hold its position without continuous Coil power. It is intended for industrial electrical control installations where maintaining contactor state after actuation is required, and it conforms to recognised product safety standards.

Features and Benefits:

• Compatible with AF and NF contactors for flexible integration
• Mechanical latching operation reduces continuous Coil power consumption
• WRB-600 series design for modular accessory mounting
• Conforms to UL 60947-1 for recognised safety criteria
• Meets CSA C22.2 No. 60947-1-13 for Canadian electrical standards

Applications

• Suitable for use in motor starter panels requiring maintained contactor position
• Ideal for control cabinets where reduced Coil duty is needed
• Used with AF contactors to add mechanical retention functionality
• Can be used for NF series contactors in industrial automation systems

How does the latch affect Coil power requirements during hold conditions?

Once engaged, the mechanical latch maintains contact closure without continuous current to the coil, lowering electrical hold demand in control circuits.

Is this accessory compatible with both AF and NF contactor ranges?

Yes, it is designed specifically to fit and operate with contactors from both ranges, allowing straightforward retrofitting or new‑panel installation.

What approvals indicate suitability for regulated installations?

The unit carries approvals aligned with UL 60947-1 and CSA C22.2 No. 60947-1-13, showing it meets referenced safety performance requirements for industrial equipment.

Can this latching unit be used as a replacement part within WRB-600 configurations?

It serves as the designated mechanical latching accessory for WRB-600 configurations and is intended for substitution or addition in compatible assemblies.
