ABB 1SBN01 Series Auxiliary Contact Block, 4A Contact Current, 690V Contact Voltage - 1SBN011421R1008

This auxiliary contact Block provides auxiliary switching for control and signalling circuits in electrical and automation systems. Fitted to the side of compatible devices, it offers a Compact means to add additional contacts for status monitoring or interlocking within control panels and machinery. Its configuration suits integration where small ancillary currents and clear change-of-state indication are required.

Features and Benefits:

• 1NO1NC configuration for combined make and break feedback
• Rated insulation voltage 600V enabling moderate-voltage applications
• Contact current 4A for low-power switching tasks
• Operational current Ie 2A for reliable control circuit performance
• Mechanical durability 10Mcycles for extended operational life
• Screw terminals for secure, maintenance-friendly connections

Applications

• Suitable for interlock signalling in motor starters and contactors
• Ideal for control-logic feedback in automated assembly lines
• Used with control relays for PLC input expansion
• Can be used for safety indication circuits in switchgear
• Suitable for retrofitting side-mounted contact monitoring

How is the Block mounted to existing equipment?

It attaches via a side-mount arrangement designed to fasten to the lateral Interface of compatible contactors or modular devices, allowing straightforward addition without altering the primary device footprint.

What Terminal arrangement does it provide for wiring?

The unit uses screw-type terminals to accept conductor connections, facilitating firm clamping and straightforward field wiring and replacement.

What switching capacity can I expect for auxiliary circuits?

Contacts are rated for a maximum switching current of 4A while the assigned operational current parameter is 2A, making it suitable for signalling and low-power control functions.

Which approvals cover its use in international installations?

It meets recognised UL and CSA ratings identified as A600 Q300, indicating conformity with specified North American contact performance categories.
