Halfgeleiderverwarming 100W voor DIN-rail

Control cabinet builders and maintenance technicians often face condensation and low temperatures inside electrical enclosures, which can lead to corrosion and equipment failure. This 100 W semiconductor heater mounts directly onto a standard 35 mm DIN rail and provides reliable, self-regulating warmth to keep your components dry and within safe operating limits.

Key specifications

• Heating power: 100 W
• Nominal voltage: 230 V AC/DC (120–240 V AC/DC range)
• Heating element: PTC (positive temperature coefficient) – self-regulating, no external thermostat needed
• Mounting: 35 mm DIN rail (EN 60715)
• Connection: 2-pole push-in clamp terminals
• Housing: UL94 V-0 rated plastic, black
• Protection class: IP20
• Operating temperature: -45 °C to +70 °C
• Approvals: VDE, UL, cUL

Why choose it

The PTC element automatically adjusts its output as the enclosure temperature changes, preventing overheating and saving energy. The compact design fits easily into crowded panels, and the push-in terminals make wiring quick and tool-free. With a wide AC/DC input range, it works with most control circuits.

Ideal use cases

• Preventing condensation in outdoor or unheated electrical enclosures
• Maintaining minimum operating temperature for sensitive electronics
• Anti-freeze protection for instrumentation and control panels
• Replacing failed heaters in existing installations

Good to know

Keep at least 50 mm clearance around the heater for proper airflow. The unit is maintenance-free and has a long service life thanks to its solid-state PTC technology. It is not suitable for use in wet or dusty environments due to its IP20 rating.
