RC4-2/50 Surge Suppressor

The RC4-2/50 surge suppressor is engineered to mitigate voltage spikes and dampen high-frequency oscillations in control circuits. It effectively limits overvoltage peaks generated during the operation of AFC-series contactors, preventing potential damage to coils and related circuit components. Compatible with block contactors including AFC40, AFC52, and AFC65 series models, the unit ensures system reliability in demanding industrial environments.

 

Constructed with screw terminals for secure connections, it accommodates various wire types: flexible conductors with ferrules (0.75–2.5 mm²), rigid solid or stranded wires (1–2.5 mm²) with a stripping length of 10 mm each. The device supports tightening torque values of 1.2 N·m for IEC configurations and 11 in·lb under UL/CSA standards.

 

Designed for AC control circuits rated at 24–50 V operating frequency (50/60 Hz), the RC4-2/50 is fully compliant with global directives such as RoHS II (EU Directive 2011/65/EU & amendment 2015/863) and WEEE regulations applicable to business-to-business transactions.

 

With compact dimensions—36 mm width, 44 mm depth, and a height of 32 mm—the suppressor fits seamlessly into constrained spaces while maintaining an operating thermal range between -20°C and +70°C (-40°C to +80°C storage). Certifications include CE conformity for EU applications alongside UL recognition ensuring adherence to rigorous North American safety standards.

 

Ideal for safeguarding low-voltage switch technology systems against electrical stress events, this accessory is pivotal across industries requiring precise control circuit protection mechanisms within small equipment classifications (<50 cm external dimensions).
