Description
• The first and most reliable surface mount telecom circuit
protector designed to protect against power cross faults
and comply with all surge requirements.
• Allows compliance with telecom regulatory standards
including Bellcore GR 1089, UL 1950/60950, and FCC part
68. Application circuit testing is recommended.
• Eliminates the need for a current limiting resistor.
• Protects against overcurrent conditions found in telecom tip
and ring applications.
• RoHS Compliant version available (-R option)
* If the device does not open at 250% within 120 seconds, increase
current to 300% of amp rating. Device must open in 10 seconds max.
