(M)SQ(H, M, P, T, U, Z) Series: Cement Box
INTRODUCTION
CHARACTERISTICS
Cement-Box type resistors offer a choice of resistive
elements inside a white flameproof cement box. In
addition to being flameproof, these resistors are also
non-corrosive and humidity proof. The available
resistive elements are:
