Rated at 21.5 amps with a Class 20 trip characteristic, this relay provides reliable motor protection in demanding industrial and commercial control panel applications. It connects via lug terminals and carries an IP20 rating, making it suitable for enclosed control cabinet installations. Licensed electricians and motor control technicians typically specify this relay when building or servicing motor starters.\u003c\/p\u003e\n\u003cp\u003eThe 1303000800 is part of LS ELECTRIC's Metasol series, which covers IEC contactors and overload relays across 25 models in 9 frame sizes. This MT-63 frame relay is paired with MC-50a and MC-65a contactors in 65AF motor control assemblies. It is front- or side-mountable and supports DIN rail installation without additional tools. The screw-type lug terminals simplify field wiring, and two built-in normally open contacts are included for control circuit integration.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21.5-amp current rating with Class 20 trip characteristic for motor protection\u003c\/li\u003e\n  \u003cli\u003eIEC-rated MT-63 frame relay for use in 65AF motor control assemblies\u003c\/li\u003e\n  \u003cli\u003eLug terminals for straightforward field wiring connections\u003c\/li\u003e\n  \u003cli\u003eIP20 rated for use in enclosed control panels and cabinets\u003c\/li\u003e\n  \u003cli\u003eDIN rail mountable without extra tools; front- and side-mount accessories available\u003c\/li\u003e\n  \u003cli\u003eTwo built-in normally open (NO) contacts included for control circuit use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with MC-50a and MC-65a IEC contactors in 65AF Metasol series motor starter assemblies.
