C - Cable switch module	F - Cable switch module	V - Cable switch module
D - Direct cable connection module	De - Direct cable connection module with earthing switch	M - Metering module

Modularity and external busbar
All modules except the metering module and circuit-breaker module are only 325 mm wide.

Transformer protection
iSafering offers a choice between a switch fuse combination and circuit breaker with relay for transformer protection. The switch fuse combination offers optimal protection against short-circuits, while the circuit breaker with relay option offers better protection against low overcurrents. Circuit breaker with relay is always recommended for larger transformers.

Normal operation conditions
The rated characteristics of the switchgear are valid under the following ambient conditions:
minimum ambient temperature: - 25 °C
maximum ambient temperature: + 40 °C

Standards
Safering/safeplus type GRM serie is tested according to following
IEC-standards:
IEC 62271-1/IEC 62271-100/IEC 62271-102/IEC 62271-103/IEC 62271-105/IEC 62271-200/IEC 60529:
