Key Features
Part #:SE-330-00-00
SKU #: 2242399
Brand: Littelfuse
Amperage Rating: 4/20 mA
Contact Configuration: 2 Form A/2 Form C
Dimensions: 3.9 in W x 5.8 in D x 8.4 in H
Series: SE-330
Type: Universal
- 100 trip records with date and time stamp
- A mini-USB interface to view measured values, configure settings and check event records using SE-MON330 v3.0 or later
- An on-board microSD card (included) can be used for long term data logging and firmware upgrades
- Ground-fault trip level is adjustable from 2-to 100% in 10 discrete settings, and in 1% increments when using the MEM setting and SE-MON330 v3.0 or later
- Dual ethernet ports are optionally available with support for fiber and RJ45 interfaces
- IEC 61850 protocol is optionally available (release is pending)
- Connect the SE-330 to the network using a standard ethernet patch cable
- Use of a crossover cable to connect the SE-330 directly to the computer running IP config is not recommended
- A typical router will assign an IP address to all connected computers that are using DHCP
- The SE-330 does not support the use of DHCP
- If the SE-330 is being set-up for first time, it is recommended to only have one SE-330 connected to the network to prevent communication errors
- 50G, 50N, 51G, 51N, 59N and 86 IEEE devices
- Fail-safe/non fail-safe relay contact operating mode
- Advance ground-fault and neutral-grounding
- Continuous NGR monitoring

Additional Description: LTFS-SE-330-00-00 NEUTRAL-GROUNDING-RESISTOR MONITOR
Catalog Description: The SE-330 is an advanced ground-fault and neutral-groundingresistor monitoring relay that is compliant with Rule10-302 of the 2018 Canadian Electrical Code Part I (CE Code). It measures neutral current, neutral-to-ground voltage, and neutral-to-ground resistance. It provides continuous monitoring of the neutral-to-ground path to verify that the neutral-grounding resistor (NGR) is intact and that it has not been bypassed or shorted. An open NGR renders currentsensing ground-fault protection inoperative and could result in a false belief that the system is functioning properly. A shorted NGR results in higher-than-expected ground-fault current. The SE-330 can be used with low- and medium-voltage transformers and generators with low- or high-resistance grounding used in processing, manufacturing, chemical, pulp and paper, petroleum, and water-treatment facilities. For high-voltage applications, use the SE-330HV. For applications that require conformance to Australian standards, use the
