Why Choose the ABB NS22E-26 Contactor Relay?
The ABB NS22E-26, product code 1SBH101001R2622, is a compact and reliable four-pole contactor relay designed for switching auxiliary and control circuits in industrial automation systems. Its balanced 2 normally open and 2 normally closed contact configuration makes it particularly useful for control logic, signalling and electrical interlocking.
Part of the ABB NS contactor relay series, the NS22E-26 combines dependable electromechanical switching with a compact enclosure and secure screw-terminal connections. It can be installed on a DIN rail or fixed directly to a panel, providing flexibility for machine builders, panel manufacturers and maintenance engineers.
With a 230 V AC, 50 / 60 Hz operating coil and an AC-15 operational current of 3 A at 400 V AC, the NS22E-26 is suitable for controlling contactor coils, indicator circuits, interlocks and other industrial control loads. Its four integral contacts allow multiple circuit states to be changed simultaneously.

Reliable Auxiliary and Control-Circuit Switching
Contactor relays such as the ABB NS22E-26 use an electromagnetic coil to change the state of several auxiliary contacts simultaneously. This allows a single control signal to operate interlocks, status indicators, contactor coils and other control-circuit devices in a predictable and repeatable sequence.
The combination of two normally open and two normally closed contacts provides complementary switching without requiring separate relays. This configuration is well suited to industrial control panels where compact dimensions, clear circuit isolation and reliable electromechanical operation are required.
Typical Applications
- Industrial control and automation panels.
- Electrical interlocking circuits.
- Motor starter control systems.
- PLC output interface circuits.
- Machine status and alarm signalling.
- HVAC and building-services control equipment.
