RC4-2/130 Surge Suppressor

The RC4-2/130 Surge Suppressor effectively mitigates high-voltage surges and pre-damping voltage frequencies generated during contactor coil operations, safeguarding sensitive control circuits from transient overvoltage events. Engineered for compatibility with AFC40, AFC52, and AFC65 block contactors, this suppressor is optimized for 50 Hz/60 Hz control circuits within a voltage range of 50–130 V AC. Its robust construction features screw terminals designed to accommodate various wire types: flexible ferrules (0.75–2.5 mm²), rigid solid (1–2.5 mm²), and stranded conductors in compliance with UL/CSA standards.

 

Installation is streamlined by precise terminal specifications including a wire stripping length of 10 mm and tightening torque values of 1.2 N·m (metric) or 11 in·lbs (UL/CSA). Compact dimensions—36 mm width, 44 mm depth, and 32 mm height—and lightweight design at just 15 g facilitate integration into confined control panel spaces without compromising performance or reliability.

 

Designed to operate under demanding conditions, the RC4-2/130 performs reliably across ambient temperatures ranging from -20°C to +70°C in operation and -40°C to +80°C during storage. The unit adheres fully to RoHS II directives as well as CE and UKCA conformity standards ensuring compliance with global regulatory requirements for electrical safety and environmental sustainability.

 

Suitable for diverse industrial applications requiring advanced low-voltage surge protection solutions, the RC4-2/130 combines precision engineering with durability to enhance the longevity of critical electrical components while maintaining operational efficiency.
