Finder Control Cabinet Heater 25 W (7H.51.0.230.0025)

Condensation and low temperatures inside electrical enclosures can cause corrosion, faulty switching, and premature component failure. This 25 W control cabinet heater counteracts those risks by maintaining a stable internal temperature and preventing moisture buildup.

Who is it for

Panel builders, maintenance engineers, and machine operators who need reliable frost protection and anti-condensation heating for small to medium control cabinets, distribution boards, or outdoor enclosures.
