Sta-Kon MTB1-TB – Frequently Asked Questions
1) What are the voltage and current ratings on the Sta-Kon MTB1-TB terminal block?
The MTB1-TB is rated 300 V and 40 A. That covers typical control panel and line-voltage branch circuit work inside those limits, so size your conductors to stay at or under 40 amps on any one circuit through the block. Anything above 300 volts needs a higher-rated block.
2) Is the Sta-Kon MTB1-TB a UL listed terminal block?
It carries UL file E66436. For an MRO or institutional buyer standardizing on UL-recognized components in control enclosures, that file reference is what an inspector or spec reviewer will want quoted alongside the 300 V, 40 A ratings.
3) Can I use the MTB1-TB on a 480 volt motor circuit?
No. The block tops out at 300 V, so a 480 V circuit is outside its rating and you need a block rated for the higher voltage. Up to 300 V and 40 A it is fine.
4) Is the Sta-Kon MTB1-TB made in the USA?
Country of origin is the United States. That matters if you are buying against a Buy American or domestic-preference clause on a government, healthcare, or education project, where the origin line has to be documented on the submittal.
5) What part number do I order for the Sta-Kon terminal block, and are there other versions?
Order it as Sta-Kon MTB1-TB. It is a single configuration, so there is no finish, color, or size to specify on the order, just the one part number.
6) What are the current-carrying parts of this terminal block made of?
Brass. Brass conductive hardware is standard for screw-clamp terminal blocks because it holds thread torque and takes copper conductors without the galvanic issues you get mixing metals. The body is black.
