Isobar 4 Evo MCB pan assemblies Replacement distribution board interiors N type SP&N and TP&N MGPA12N Application for N type single phase and neutral The standard N range of pan assemblies is designed to suit single and double pole applications. The pan assemblies are exactly the same as those used in Isobar 4 Evo "A" boards. Each pan assembly is comprised of a folded sheet steel back plate incorporating a hook and bolt fixing systems, inbuilt stand offs, DIN rail, incoming and outgoing SP & DP busbar assemblies, neutral and earth terminal bars. N type pan assemblies are suitable for use in systems which include circuits where the neutral should be switched/protected, eg. Petrochemical industry, or any system where the neutral may represent a hazard. Any mix of SP and switched neutral devices can be used. The NKIT converts any outgoing way from phase to neutral and permits the use of DP devices.

The pan assemblies are exactly the same as those used in Isobar 4 Evo B type boards and can be used as replacement interiors. Each pan assembly comprises fixing feet incorporating DIN rail, incoming and outgoing busbar assembly and neutral terminal bar. They can be easily and quickly incorporated into custom built enclosure systems. N pan assemblies are designed for use with SP, DP, TP and 4P C60H MCB, and are also suitable for two pole two phase equipment.
