Novaris - Intrinsically Safe Protectors | IS-SLT Get latest price

Intrinsically Safe & Flameproof Instrument Protectors 

The intrinsically safe and flameproof IS-SLT range provides surge protection for most twisted pair signal cables associated with intriscally safe field devices.

IECEx & ATEX approved

Novaris ‘IS-SLT’ products are certified intrinsically safe and flameproof according to IEC Ex and ATEX and so may be installed in Ex d rated instruments without loss of integrity

Multistage design

The multistage design provides a high-energy gas discharge tube (GDT) as primary protection for common-mode disturbances, commonly associated with lightning strikes and power system earth faults, and a secondary metal-oxide varistor clamping stage across the signal lines. This combination provides very robust surge protection with high transient suppression and low let-through voltages. In addition, protection is provided for cable screens which may be open circuits at the instrument.

IS-SLT-Y Adapter

Where a field instrument has no free cable entry Novaris can supply a Y-piece
adapter to accommodate the threaded instrument protector and cable gland.
