Siemens 3NE8017-1 Electrical Safety Relay Module

Siemens 3NE8017-1 is a SITOR fuse link (NH00) with blade contacts rated at 50 A, designed as a back-up fuse link for semiconductor protection. It carries a gR interrupt rating and supports connection up to 690 V AC or 440 V DC, with a visible front indicator for status at a glance. The device specifies coordination type 2 and an Iq of 65 kA, enabling selective protection within safety or semiconductor protection architectures. This fuse link is intended for use in Siemens and compatible protection schemes where NH00 fuses are specified, providing reliable overcurrent interruption in control cabinets while allowing straightforward replacement via blade contacts.
