Eaton HT8B – Frequently Asked Questions
1) Is the HT8B a normally open or normally closed contact?
Normally closed. The HT8B carries a single NC contact, so the circuit is made at rest and breaks when the operator is actuated. If your control scheme needs a circuit that closes on actuation, you need an NO block instead.
2) How many Eaton HT800 contact blocks can I stack on one pushbutton?
Eaton's catalog guidance for the HT800 line is a maximum of four contact blocks per side, eight total, on a single operator. Past that, switching reliability suffers. Plan your stack count before you buy blocks for a multi-circuit station.
3) Can this contact block be used in a washdown or oily machine area?
It is built to Eaton's Watertight/Oiltight HT800 standard, which is what you want for wet, damp and oily industrial areas, machine control circuits and enclosures exposed to coolant or washdown. The sealing performance comes from the HT800 operator and enclosure it is installed behind.
4) Is the Eaton HT8B contact block UL Listed for industrial control panels?
Yes, the HT8B is UL Listed, which is the listing panel builders and inspectors look for on pilot device components in commercial and industrial control applications.
5) How much room do I need behind the panel for the HT8B block?
Figure 1.3 in wide, 1.9 in deep and 2.2 in high for the block itself, then add the depth of the operator it mounts to and any additional blocks you stack. In a shallow enclosure that back-of-panel depth is usually the constraint, not the door cutout.
6) Does the HT8B come with a guard?
No. The HT8B is the without-guard configuration, giving a slimmer profile for tight panel layouts where a protective guard is not called for. If your spec calls for a guarded block, that is a different part number in the HT800 family.
7) What is the part number to order this Eaton NC contact block?
Order Eaton HT8B. That is the manufacturer part number for the 30.5 mm HT800 normally closed contact block without guard.
