£94.23
The Finder 7H.51.8.110.0250 is a compact and reliable 250 W fan-assisted PTC panel heater designed to prevent condensation and maintain suitable temperatures inside electrical control cabinets and industrial enclosures. As part of the Finder 7H Series enclosure heater range, it combines self-regulating positive temperature coefficient (PTC) heating technology with forced-air circulation to protect sensitive electrical and electronic equipment from moisture-related problems.
This industrial enclosure heater uses an integrated fan to distribute warm air throughout the cabinet, helping reduce cold spots and maintain a more consistent internal temperature. Its self-regulating PTC heating element automatically adjusts its electrical resistance as its temperature increases, providing efficient heating characteristics without relying on a conventional fixed-resistance heating element. The compact aluminium-profile construction supports effective heat transfer, while the integrated fan improves air circulation within enclosed electrical installations.
With a maximum heating power of 250 W, a 110 V AC nominal supply and an integrated fan delivering approximately 30 m³/h airflow, the Finder 7H.51.8.110.0250 is ideal for industrial control panels, automation cabinets, electrical distribution enclosures and machine control systems. Its 35 mm DIN rail mounting and fast wiring terminals simplify installation inside electrical cabinets.
Electrical enclosure heaters such as the Finder 7H.51.8.110.0250 help protect industrial electrical equipment by maintaining the internal cabinet temperature above the dew point. Condensation can develop when moisture in the air encounters cooler surfaces inside an enclosure, potentially causing corrosion, insulation deterioration and electrical faults. By introducing controlled heat and circulating warm air, the heater helps reduce the likelihood of moisture forming on sensitive electrical components.
The Finder 7H.51 Series is designed for industrial cabinet temperature management and can be used with a suitable external thermostat for automatic heating control. Its self-regulating PTC element and integrated fan provide effective warm-air distribution, while the DIN rail mounting system enables convenient integration into electrical cabinets. Correct installation requires adequate ventilation clearance, appropriate electrical protection and sufficient thermal capacity for the enclosure. The heater must not be covered, and its surfaces can remain hot for approximately 15–20 minutes after disconnection.

The Finder 7H.51.8.110.0250 is a 250 W fan-assisted panel heater designed to prevent condensation and maintain suitable temperatures inside industrial electrical cabinets, automation panels and equipment enclosures.
The heater operates from a nominal 110 V AC supply at 50/60 Hz, with a permitted operating voltage range of 88–121 V AC. It is not designed for direct connection to a standard 230 V AC supply.
The Finder 7H.51.8.110.0250 provides a maximum heating power of 250 W at 20 °C ambient temperature and incorporates a fan delivering approximately 30 m³/h airflow to distribute warm air throughout the electrical enclosure.
The heater uses a self-regulating PTC heating element, but an external enclosure thermostat is recommended for automatic temperature control. A suitable thermostat can switch the heater according to the required cabinet temperature, helping maintain effective condensation protection while reducing unnecessary energy consumption.
The heater is designed for vertical mounting on a 35 mm DIN rail conforming to EN 60715 and uses fast wiring terminals for electrical connection. Installation should provide sufficient clearance for airflow, suitable overcurrent protection and safe separation from heat-sensitive components.
Finder 7H Series enclosure heaters provide dependable thermal management for industrial control cabinets, electrical distribution panels and automation equipment. The Finder 7H.51.8.110.0250 combines 250 W PTC heating technology, integrated forced-air circulation and convenient DIN rail installation to help protect electrical systems against condensation and low-temperature operating conditions.
