SR3D is a universally applicable safety relay with three safety relay outputs, specially designed for the use in furnaces in continuous operation according to EN 50156-1. Additionally, it is certified by the Germanischer Lloyd under 32915-06HH and thus, approved for use at sea.For example, it is being successfully used in waste incineration plants on ships.
For contact protection, miniature circuit breakers (MCBs) rated at 3A (max.) with trip characteristics Type A, B, or C are permissible as an equivalent alternative to a fuse.
