Raychem SBS-xx-SNR Control Cabinet for Sprinkler System Frost Protection
Description
[Image Description: A white, rectangular electrical control cabinet with a grey door. The Raychem logo is visible in the upper right corner. The door has several indicator lights, switches, and labels. It appears to be a robust industrial unit.]
The Raychem SBS-xx-SNR control cabinet is an integrated complete solution for controlling self-regulating Raychem heating cables for frost protection of pipelines in sprinkler systems. In accordance with the requirements of BS EN 12845:2008, it features a multi-regulator/multi-sensor thermostat control with automatic switching functionality to a redundant heating circuit.
Models in this series control 2-12 heating circuits of frost protection heating cables, utilizing up to 12 regulators and sensors (one per primary and redundant heating circuit). For safe operation, the control cabinet is equipped with circuit breakers (C-characteristic) and a residual current device (RCD). The cabinet is pre-wired and only requires connection to the mains power supply (400 V, three-phase alternating current).
Advantages
- Quick connection of multiple heating circuits directly to the control cabinet.
- No additional connections or junction boxes required.
- Connection of 2-12 heating circuits with maximum length on a single control cabinet.
- Automatic switching to a redundant heating circuit as per BS EN 12845:2008.
- Circuit breakers/RCD directly integrated into the control cabinet.
- No separate safety components required.
- Digital temperature measurement on each sprinkler line.
- Alarm for heating circuit failure (and automatic switching to a redundant heating circuit).
- Complete system directly from the manufacturer.
- System and components are specifically selected and matched for optimal performance in sprinkler system frost protection.
