Standard Block: Series B and later can be mounted 2 per level up to 2 levels and can be mixed with
other block types. Series A can be mounted 1 level only and cannot be mixed with other block types.
See Note 5 for restrictions on use of 800T/TC-XD3 block.
Self Monitoring Block: Units are only functional on level 1. Units can only be used with 2
position devices. Travels of the self monitoring contacts are not suitable for 3 & 4 position
selector switches, 3 position push-pull units and toggle units.
MaxDuty: Intended for high-current or horsepower-rated applications. Recommended for use
with maintained push button operators. Can be mounted 2 per level up to 2 levels and can be
mixed with other block types.
Mini Block: This block is intended for use with either the standard contact block or the sealed switch
logic reed contact block, but should be used on level 2 only. Uses special short mounting screw.
Sealed Switch — Hi Current: Can be used only on level 1. Can be mounted alongside a stack of
2 other types of blocks. Should not be used on the following operators: 800T-K selector pushbuttons
and 800T-T 2, 3, & 4 way switch series P and earlier.
Sealed Switch — Medium Current: Can be mounted 2 per level up to 2 levels. Can be mixed with
other types of contact blocks. Uses special mounting screw with extended head.
Sealed Switch — Logic Reed: Can be mounted 2 per level up to 2 levels. Can be mixed with other
block types.
ATTENTION: Extender is for level 2 installations. Contact blocks used on operators
with posts at 2 or 4 corners of adapter plate must be mounted without spacer. Sealed
switch contact blocks should be handled with care. Do not drop.
Note:
1) The contacts in the sealed switch contact blocks are hermetically sealed in a glass envelope. Dust,
dirt, oxidation, oil laden air, or other air borne contaminants do not affect the continuity of the
contacts.
2) The contacts in the standard and mini contact blocks and the operating mechanism of all the
blocks are not sealed, and should not be exposed to harsh environments.
3) The sealed switch contact blocks are suitable for use in certain hazardous environments. When
mixing standard or mini contact blocks with sealed switch contact blocks in these environments,
care should be taken to insure that all safety requirements are met.
4) Never blow dirt off of electrical components. This may force the dirt into internal mechanisms
– use vacuum.
5) Cat. No 800T/TC-XD3 contact blocks should not be used with the following Selector Switch
Operators.
