Special MMP enclosures with IP40, IP55 or IP65 degrees
of protection are available surface mount or installed and
feature protection against direct contact, solid foreign bodies
and dust, as well as the ingress of water. Whether equipped with
protective membranes, locking devices or an emergency stop
button, the XTPB will meet your application requirements. XTPR Rotary Actuated MMP
XTPR MMPs offer a solution for applications from 0.1 to 63A in
two small frame sizes. The 63A XTPR has a width of just 55mm,
the smallest MMP in the industry! Enclosures with black or
red/yellow covers are available for North American and IEC
applications in IP41, IP55 or IP65 degrees of protection. XTPR
enclosures are available for MMPs with front mount auxiliary
contact modules including those with the early-make contact.
Padlock attachments and a rotary handle mechanism kit make it
easy to mount the XTPR in any enclosure.
