Low-voltage electrical cabinets

Low-voltage electrical cabinet

Advantages

  • Wide range of standard cabinets
  • Controller for de-icing system is included
  • Accessories by leading global producers of electrical equipment
  • Dust and moisture ingress protection rating IP41-IP66
  • Electric current leakage and short circuit protection
  • System performance status indication
  • Design and manufacture of nonstandard cabinets
  • By order: integrated heating, implementation of mechanism for starting current decrease

The electrical low-voltage cabinets are designed as an electrical power system and to implement control functions for a de-icing system.

The cabinet includes:

  • digital temperature controller (refer to the section “Control equipment”);
  • starting and protective equipment (automatic power circuit breakers, protective cutout devices, starters, power supply unit for a precipitation sensor);
  • control and alarm devices (relays, indicator lights);
  • equipment for internal heating of cabinet (optionally as also for some standard cabinets).

Features

The cabinets including the digital temperature controller РТ-330, are designed for comparatively small systems which operate in stable climatic conditions.

The cabinets including the controllers РТ-200 and РТ-220, ensure the maximum weather adaptation and the most saving electrical power consumption.

By order, the control cabinets for any nonstandard electrical heating systems can be produced. All the cabinets are completed with a protective cutout device on 30 mA.

The cabinets with the controllers РТ-200 and РТ-220 are completed with the power supply unit for a precipitation sensor.

Temperature, precipitation and water sensors are purchased separately.

The wall-mounted control cabinets have plastic enclosure.
