  • Merlin 500S (Utility Isolation Panel)

The Merlin panel is designed to provide the user with an effective means of isolating the utility, via a key switch or in the event of an emergency, by operation of the emergency shut off button. The key operated 500S is UK manufactured and like all S & S Northern products carries a 3 Year warranty and is fully supported by our technical team. The 500S has a fascia mounted emergency shut off button fitted as standard and the fascia mounted LEDs give simple and concise information to the operator. The panel is fully compatible with S & S Northern remote emergency stop terminals allowing a large number of emergency terminals to be connected in series and wired back to the panel. The 500S is an excellent isolation panel. Simple to fit with little maintenance required and is covered by the full support that comes with the entire range of Merlin products.
