Why Choose the ABB VA7910 Anti-Condensation Heater?
The ABB VA7910 is a compact 100 W anti-condensation heater designed for temperature management inside industrial electrical cabinets and automation enclosures. It helps prevent condensation by maintaining a controlled level of heat within the enclosure, protecting installed electrical and electronic equipment from moisture-related operating problems.
The VA7910 uses a PTC thermistor heating element combined with an aluminium-alloy heat-dissipation structure. PTC technology automatically changes impedance according to operating temperature, providing intrinsically stable heating characteristics and dependable operation across the supported supply-voltage range.
With a rated heating power of 100 W, a 110–240 V AC/DC supply and the authoritative product specification of 160 × 82 × 42 mm, the VA7910 is suitable for industrial control cabinets where condensation must be minimised. The heater is intended for 35 mm DIN rail mounting and requires thermostat control for the installation.

Reliable Condensation Control for Electrical Enclosures
Condensation can form inside electrical cabinets when changes in ambient temperature cause internal surfaces to fall below the dew point. An enclosure heater raises the internal temperature sufficiently to reduce this risk, helping maintain a more suitable environment for switchgear, controls, drives and other electrical equipment.
The ABB VA7910 uses a self-regulating PTC heating element whose electrical characteristics vary with temperature. Installed on a 35 mm DIN rail and operated through a suitable thermostat, it provides a compact temperature-management solution for industrial automation and electrical cabinet applications.
Typical Applications
- Industrial electrical control cabinets.
- Automation and machine-control enclosures.
- Switchgear and distribution enclosures.
- PLC and instrumentation cabinets.
- Electrical cabinets exposed to changing ambient temperatures.
- Industrial installations requiring condensation prevention.
