What to check before ordering

• Breaking capacity class (B, C, N, S, H, L, V) must match the installation's prospective fault current.
• Fixed, plug-in and withdrawable versions are not interchangeable without the matching base.
• Thermomagnetic trip units are adjustable within a band — confirm the band brackets your load current.
• Note that this catalog lists Tmax XT items by their full descriptive type designation rather than a short order code; send us the details and we will match it.

Frequently asked questions

How do I read a Tmax XT type designation?

It states the frame (XT1/XT2/XT3/XT4), the breaking class letter, the frame current, the trip unit type and rating band, the terminal type, the number of poles and the reference temperature — for example XT1C 160 TMD 100-1000 F F 50°C 3P.

What replaced the older Tmax range?

Tmax XT is the successor to the earlier Tmax T generation.
