- Options A=3, A=8, and A=10 were all for Ex d IIB T6 Gb. These
are now replaced by the A=4, A=9, and A=11, respectively, which
reflect the same approvals but with addition of the H2 gas group.
- Options A=0 through A=4 are only compatible with B=1 or B=2.
Options A=5 through A=9 are only compatible with B=3 or B=4. - INMETRO approvals (A=11) available with silver relay contacts only
(B=1 or B=2)
- When options C=2 and D=3 are simultaneously specified (2g, 24Vdc
reset coil), the switch sensitive axis (see Figure 1 for 5550 and
Figure 2 for 5550G) MUST be oriented vertically with the cover facing up. This coil lacks sufficient holding strength to support the trip
plate when the switch is mounted horizontally or upside down. The
switch may be mounted at any orientation for all other options.
- Consult Figure 1 for mounting plate dimensions corresponding to
E options.
- UL US/CA approvals require tapered threads for conduit and are
not compatible with option E=4, 6, or 8.
- If left blank, option 0 is provided.
- Estimated Lead Time: 4 - 6
- Shipping Weight: 3 Kg
