PTC resistance heater 55W 110/250V NSYCR55WU2

Universal resistance heater for control cabinets and more

This 55-watt PTC resistance heater is a reliable solution for maintaining optimal temperature inside control cabinets, electrical distribution boards, connection boxes and other enclosures. Thanks to its wide power supply range (110…250V AC), it is compatible with various electrical installations. Its compact dimensions (85 mm width, 200 mm height and 70 mm depth) allow for easy integration even in limited space.

Construction and application

The heater uses PTC (Positive Temperature Coefficient) technology, which means its electrical resistance increases with temperature. This provides self-regulation and prevents overheating, increasing safety. Made of extruded aluminum, it effectively dissipates heat and ensures long-term operation. Designed for mounting on a 35 mm DIN rail using clips, which facilitates installation and servicing. It can be used in applications requiring protection against moisture and dust (IP20 protection class).

Key advantages and features

• Wide voltage range: Compatibility with 110-250V AC (50/60 Hz) installations – versatility of application.
• PTC technology: Self-regulation of temperature and overheating protection – increased safety and reliability.
• Compact dimensions: Easy integration in limited space – ideal for control cabinets and distribution boards.
• Durable construction: Extruded aluminum housing provides efficient heat dissipation and long life.
• Easy installation: Mounting on a 35 mm DIN rail using clips – quick and easy installation.
