Supplier Description & Specifications:

RESYS P40 panel mount type A differential relay (earth leakage protection)

RESYS M40 earth leakage relays associated with a remote trip breaking device (automatic power breaking), provide the following functions:

• Protection against indirect contact
• Limitation of leakage currents

They also preventively monitor electrical installations via a (configurable) pre-alarm function or when used as a signalling relay.

Features:

• Positive or negative security
• Panel mount (48 x 48 mm)
• 2 relays with configurable function (alarm or pre-alarm at 50% (I△n)
• Adjustment of I△n: 0.03 – 0.1 – 0.3 – 0.5 – 1 – 3 – 5 – 10 – 30A
• Time delay: 0 – 0.06 – 0.15 – 0.30 – 0.50 – 0.80 – 1 – 4 – 10 second
• LED bargraph provides real-time display of leakage currents
• Tripping accuracy by TRMS measurement (improves immunity to nuisance tripping)
