❓ Frequently Asked Questions

Q: What does the 2 NO (Normally Open) contact configuration on the 5ST3011 mean?

A: These contacts change state when the device is operated or energised. Size the contact for the actual switched load — pilot duty ratings are typically lower than the main contact rating.

Q: What is the difference between an RCBO and a standard MCB — and why use the 5ST3011?

A: A standard MCB protects against overload and short-circuit only. An RCBO combines MCB overcurrent/short-circuit protection AND RCCB earth leakage detection in a single 1-module device — ideal where both forms of protection are needed in limited panel space. Choose the 5ST3011 when the application specifically requires rcbo characteristics.
