Rittal 3105310 Cabinet Heating Resistor 8-10W

Product Description

The RITTAL 3105310 is a cabinet heating resistor rated at 8 to 10 watts, designed to prevent condensation and moisture buildup inside electrical enclosures and control cabinets. Low-wattage resistive heating elements like this one maintain the internal temperature of a cabinet above the dew point, protecting sensitive components from corrosion and moisture damage. The unit measures 3.07 inches x 2.36 inches x 3.54 inches and weighs 0.42 pounds, making it a compact solution for space-limited enclosure installations. Electricians and panel builders typically specify this type of heater during enclosure assembly or when retrofitting moisture control in existing cabinet installations.

This heating resistor is intended for use inside electrical enclosures and control panels where ambient temperature differentials can cause condensation. It is suited for both industrial and commercial panel applications where low-level continuous heat is needed to maintain safe operating conditions for relay banks, terminal blocks, drives, and similar components. The compact form factor allows installation in enclosures with limited interior clearance.

Key Features

• 8 to 10 watt resistive heating output for low-level continuous anti-condensation duty
• Compact enclosure profile at 3.07 inches x 2.36 inches x 3.54 inches
• Lightweight at 0.42 pounds for easy handling and mounting
• Designed to protect enclosure components from moisture and condensation damage
• Suitable for retrofit or new-build panel assembly applications

Compatibility

Designed as an OEM-style replacement or supplemental heating element for RITTAL electrical enclosures and control cabinets requiring low-wattage anti-condensation heating.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the enclosure and verify the absence of voltage before mounting or wiring the heater. Position the unit to allow adequate airflow across the heating surface and avoid direct contact with wiring harnesses or heat-sensitive components. Follow the enclosure manufacturer's guidelines for heater placement to achieve even temperature distribution inside the cabinet.
