RMS Mors Smitt

RMS Mors Smitt is dedicated to the design, manufacture and distribution of high-quality electrical engineering products.

Major product types include:

• Auxiliary and tripping relays
• Test blocks
• Arc flash protection
• Utility grade protection and control relays
• Industrial controls and pilot lamps
• On board railway relays, CBs and panel meters

Arc flash monitoring provides arc fault protection for the fast clearance of arcing faults on BUS bars and within metal clad switchgear and associated cable boxes. The arc is detected using an optical sensor and the signal input to a protection device which also monitors the load current on the system.

RMS Mors Smitt’s range of protection relays includes:

• Timing relays
• Voltage protection
• Auto reclose and sync check
• Current protection
• Frequency sensing
• Phase monitoring / potential selector
• Transformer regulation
• Voltage regulation and tap changer control relays

The new generation of RMS Mors Smitt electro-mechanical relays is specifically designed for high-voltage protection and control applications. Multi-contact, high-speed trip relays ensure fast operation of less than 8ms. The unique patented design and topology ensures minimal contact bounce.

Test links are an important accessory for protection, metering and control panels. They enable test technicians to quickly and safely isolate protection relays so test signals may be injected and system performance verified.
