RS PRO Auxiliary Contact Block, 1 Contact, 1 NC, HRS Series, Rail Mount, 1.5 A, 240 V 121-6868

RS PRO 121-6868 Auxiliary Contact Block is a high-quality electrical component featuring 1 contact in 1 NC (Normally Closed) configuration. Part of the HRS series, this device is designed for reliable control applications with a current rating of 1.5 amperes and rated voltage of 240 volts.

It offers manual control functions through START and STOP push-buttons, which include trip indication ensuring the buttons stay in the middle position when tripped. The auxiliary contact block has an automatic switch-off mechanism for over-current events utilizing thermal or magnetic release options, enhancing operational safety and equipment protection.

The block incorporates an auxiliary switch suitable for side or flush mounting, providing a clear indication of the switching state. Its contacts are engineered from materials resistant to welding, thereby reducing contact heating and extending service life.

This auxiliary contact block is intended for mounting on standard 35 mm wide mounting rails compliant with EN 60715, enabling easy integration into electrical control panels. The unit can be installed vertically or horizontally, offering flexibility in layout design.

Manufactured with UL-approved Nylon 66 material rated 94V-2 for insulation, the black-colored housing provides robustness and durability. The design includes enlarger and reducer glands with metric threads facilitating easy cable gland adaptations.

Operating temperature ranges from -25°C to 60°C, and mechanical durability is certified for up to 100000 operating cycles, making it suitable for demanding industrial, automation, and control gear applications.
