Finder 100 W PTC DIN Rail Enclosure Heater 230 V AC 7H.51.0.230.0100

100 W PTC heating element warms control cabinets fast, with double insulation and anodized aluminum housing for reliable convection heat.

Overview

The Finder 7H.51.0.230.0100 is a 100 W enclosure heater for 35 mm DIN rail mounting. It operates on 230 V AC and uses a PTC heating element that self-regulates temperature for safe, efficient heating. The anodized aluminum profile promotes convection, distributing warmth evenly inside the cabinet to prevent condensation and low-temperature faults.
