229D (MARINE) & 279 (COMMUNICATION) CIRCUIT PROTECTORS
UL-1500 Ignition Protection
The 229D family is certified to UL-1500 which covers
Ignition Protected circuit protectors. This specification
requires devices to be used in accordance with the
requirements of U.S. Coast Guard and Fire Protection
Standard for Pleasure and Commercial Motor Craft, ANSI/
MFPA No. 302.
The ratings available are 100 amperes or less at 65Vdc or
240Vac. Maximum IC, 1000 amperes. Consult factory for
application details.
The 299D series is available with interlocking to prevent on
board and shore power being used simultaneously.
Combination of ON-OFF switching the protection function
offers a simplified solution for your electrical systems.
UL 489A Communications Equipment Protection
The 279 Series complies with the requirements of UL 489A,
Circuit Breakers for use in Communication Equipment,
meeting the need for protection at higher DC voltages.
The available ratings are 100 amperes or less at 160Vdc.
Maximum short circuit interrupting current is 5000 amperes.
The 279 series available only in a series trip configuration.
Please consult Sensata for specific application details.
209/219/229/249/279 Series - 229D (Marine) / 279 (Communications)
209/219/229 CONFIGURATIONS
Series Trip
The most popular configuration for magnetic protectors is
the series trip, where the sensing coil and contacts are in
series with the load being protected. The handle position
conveniently indicates circuit status. In addition to
providing conventional overcurrent protection, it’s
simultaneously used as an ON-OFF switch.
Auxiliary Switch
This is furnished as an integral part of a series pole in
single or multi-pole assemblies. Isolated electrically from
the protector’s circuit, the switch works in unison with the
power contacts and provides indication at a remote
location of the protector’s ON-OFF status.
