Product Short Description
Product Overview
The ABB GHV2501902R0002, also designated as model RV-BC6/60, is a compact and highly reliable varistor-based surge suppression module designed specifically for DC-operated miniature contactors . Its primary function is to protect sensitive control circuits by absorbing and dissipating high-voltage transients, commonly known as inductive kickback, generated when a contactor coil is de-energized . By clamping these voltage spikes, the suppressor extends the electrical life of contacts, reduces electromagnetic interference (EMI), and ensures the stable operation of adjacent electronic equipment within the control panel . It is engineered as a direct accessory for ABB’s B6 and B7 series miniature contactors, providing a seamless and space-saving protection solution .
Description
Key Features & Functions
-
Effective Coil Surge Protection: Utilizes a high-quality metal oxide varistor (MOV) to instantly clamp transient overvoltages produced by DC contactor coils upon switch-off, preventing insulation breakdown and contact welding .
-
Direct Mounting Design: Engineered for simple and secure attachment directly onto the coil terminals of ABB B6 and B7 series miniature contactors, eliminating the need for additional wiring or brackets .
-
Compact and Space-Saving Form Factor: Its minimal footprint allows it to be mounted directly on the contactor without increasing the overall panel space required, making it ideal for high-density control panels.
-
Simple Screw Terminal Connection: Equipped with robust screw terminals for quick and reliable electrical connections, ensuring a stable and vibration-resistant installation .
-
No Visual Status Indication: This module performs its protection function passively and does not include an LED or other visual indicators to show operational status .
